Multi-terrain Select
(AWD models)
Multi-terrain Select is a sys-
tem that improves drivabil-
ity in off-road situations.
When driving over muddy,
sandy or rough road sur-
faces, the system selects a
suitable driving mode to
switch AWD, brake and
drive force control to per-
form control suitable for the
road condition.
WARNING
■Before using Multi-terrain
Select
Make sure to observe the follow-
ing precautions. Failure to
observe these precautions may
result in an unexp ected accident.
●Check that the Mud & Sand and
Rock & Dirt indicators are illumi-
nated before driving. Multi-ter-
rain Select will not operate
when the indicators are off.
●Do not rely solely upon the
Multi-terrain Select. This func-
tion is not inten ded to expand
the limits of the vehicle. If the
system is continuously used for
a long period of time, the load
on related parts increases and
the system may be unable to
operate normally, which may
lead to an accident. Thoroughly
check the road conditions and
driving route before driving, and
drive with caution.
